IMPROVEMENT IN PERFORATING-STAM PS.

Specification forming part of Letters Patent No. 223,161, dated December30, 1879 application filed October 27, 1879.

To all whom it may concern:

Be it known that I, HENRY H. NORRING- TON, of Nest Bay City, in thecounty of Bay and State of Michigan, have invented a new and usefulImprovement in PerforatingSt-amps; and I do hereby declare that thefollowing is a full, clear, and exactdescription of the same.

My invention is an improvement in the class of check-punches orperforating-stamps in which a horizontal die wheel or wheels rotating ona vertical axis, and carrying a series of punches, and also a slidingplunger and leverpawl, are arranged to coact in such manner that thedie-wheels are rotated by and with the plunger, and the descent of thelatter operates the punches and also the feed mechanism.

My invention is more particularly an improvem ent upon a stamp forperforating checks, drafts, 850., for which I have received UnitedStates Letters Patent No. 220,412. In said former invention tworotatable dies or die-wheels are employed, one a die provided withpunches, and the other a die provided with holes for receiving thepunches. These die-wheels are arranged horizontally on different shaftsand in differentplanes, and connected by gears in such manner that bothrotate simultaneously in opposite directions.

The punching-die is attached to a sliding sleeve or plunger, and whenforced down it operates a pawl and ratchet feed-wheel that moves thecheck, and one of the punches fixed in the under surface of such diepunctures the check or other paper placed between the two.

lower wheel is provided with movable spring punches, which are forced upthrough the check or other paper by the action of a lever that alsoeffects the rotation of the feed-wheel.

I thus economize space, simplify the constrnc= tion, lessen the numberof parts, and secure a more direct and positive action.

In the accompanying drawings, forming part of this specification, Figurel is a vertical central section on line y y of Fig. 3. Fig. 2 is avertical section on line a a: of Fig. 3. Flg. 3 is a horizontal sectionon line 22, Fig.1. Fig.

4 is a detail section, showing the operation of certain parts. Figs. 5and 6 are detail views.

A indicates the table, and B the springplate for pressing the check orother paper upon the feed-wheel O. A portion of the inner edge of saidtable A lies between the two dies D E, which are fixed horizontally 011the sleeve or hollow shaft F. The latter rotates or is rotatable on aplunger, G, arranged to slide vertically in the guide of the goose-neckor curved arm H of the base I, upon which the table Ais supported.

In my former invention, above referred to, the sleeve carrying thepunching-wheel slides vertically, whereas in this machine the same hasno vertical movement; but the plunger G is made to slide instead. Theplunger G is connected with the hollow shaft F of the diewheels D E bymeans of a-slot and feather, so that while the plunger is free to slidevertically, it carries the die-wheels D E with it in any rotarymovement.

The die D has a series of vertical-sliding punches, at, which are heldin sockets arranged concentrically near its periphery, and provided withspiral springs for retracting them, as

hereinafter described.

The upper wheel, E, has a series of vertical holes, 1), correspondingboth in number and shape and position with the punches at of the lowerwheel. These holes I) are designated in regular order or succession bythe following characters, to wit: A star, the numbers to 9, inclusive,and the cipher, (0.) The punches a, which register with these holes I),have like characters (star and numerals) cut in their upper ends, sothat when a particular punch or die, a, is forced up, it will make apuncture in the check or draft, Fig. 3, which will correspond to thecharacter by which the hole above it (the punch) is designated.

The device for forcing up the punches a in any desired order orsuccession is an angular lever, K, which is pivoted at c to a projectionor rib of the base I. The outer end of this 1ever is provided with avertical stud or finger, d, and the inner end projects beneath thehollow shaft F and rests on a spring, 0, so that when the plunger Grdescends it will tilt the lever K and cause its finger d to strike onany stud a that is brought into coincident position with it, and thusforce the same upward through the check or other paper laid on the tableA between the dies D E, as shown in Fig. 4.

Whenever the die D is so adjusted that one of its punches a. is notdirectly over the finger d of lever K, it is obvious the lever cannot betilted, and the plunger G cannot be forced down, since the said fingerwill then come in contact with the imperforate portion of the wheel D;but the characters on the upper wheel, E, being under the eyes of theoperator, it is easy for him to perceive when the proper registrationexists, and hence no difficulty is experienced in practical operation.

The lever K has an arm, 7", to which a hookpawl, g, is hinged. Aratchet-wheel, h, is affixed to the inner side of the feed-wheel C, andthe pawl g engages the same. The lever K has thus a double functiontowit, it operates the punches and the feedwheel.

In my former invention the downward movement of the plunger causes thefeed-wheel to rotate; but in this case the feed-wheel is ro tated as theplunger moves upward, since the spring at that time tilts the lever backto its original or normal position, and thus draws the hook-pawl gdownward.

In my former invention the punches tend to raise or draw the paperupward when the plunger recedes, and thus disturb the position oradjustment of the check or other paper being punched. In this machinethat difficulty is avoided, since the check lies flat on the table A,and cannot be moved while a punch is being retracted. In this machine,therefore, I simplify the construction by lessening the number of parts,economize space, and secure a more direct and positive action.

What I claim is- 1. In a perforating-stamp, the combination, with thetable A and horizontal die-wheels, both fixed on a rotatable sleeve, andthe lower one having a series of sliding punches, of the plunger slidingin, but rotating with, said sleeve, and a device arranged beneath thedie wheels, and on which the foot of the plunger acts for raising thepunches, substantially as shown and described.

2. In a perforating-stamp, the lever pivoted beneath the table andprovided with the vertical finger and lateral arm .to which the pawl isattached, the ratchet feed-wheel, and the plunger which acts on thespring-supported end of the lever, and the die-wheel carrying movablespring punches, all combined as shown and described.

3. In a perforating-stamp, the combination of the sliding plunger withthe sleeve or hollow shaft carrying the die-wheels, one of which has aconcentric series of spring-punches, said plunger extending through thesaid shaft and forming the support or axis with which it revolves, and apivoted lever which projects heneath the foot of the plunger, as shownand described, so that the plunger may be depressed, the wheels rotated,and the lever tilted simultaneously, as specified.

The above specification of my invention signed by me this 18th day ofOctober, 1879.
